. Vacuum regulation function
. M12 connection

With GVMAXV2-2 and GVMAXV2-2R, COVAL offers two solutions on a single standard electrical GVMAX base pump.
These pumps offer an ‘all in one solution’ by integrating all the necessary functions, pilots, valves, vacuum regulation, blow-off, object presence thanks to vacuum switch and silencer in a compact and light weight single module.
The M12 connecters radically simplify the installation and utilization. They are available in two versions and compatible with the safety of the automat:
• GVMAXV2-2: Non-adjustable vacuum switch (factory settings)
• GVMAXV2-2R : Adjustable vacuum switch
In comparison to the standard GVMAX the two pumps GVMAXV2-2 et GVMAXV2-2R offer the following advantages:
• Security: vacuum generation in case of electrical failure by in coming electro valve for feed pressure through normally open function (24VCC)
• Controlled and powerful blow-off system.
• Data processing circuit (connection cable)
• Connection by 2 male 5 pin M12 connectors, (Input/ Output)
• Compatible with the safety automat
